Hello everyone,
This is my first forum post here. 
I have a multi-shop Prestashop (1.7.5.2) site with two subdomains (shop1 & shop2).
The problem I am facing:
On shop1, when I go to Back-Office -> Catalogue -> Products -> Product choose -> Options tab -> Customization Head
and enter the some Customization text as a Text Field for one shop (check screenshot attached). On saving, it gets saved but the Text Field disappears from the shop2. The same behavior occurs when I save the Text Field from the shop2. I cannot simultaneously have the Customization text fields on both shops.
(The same issue occurs on Prestashop version 1.7.7 also)
I looked into the code and found that in `src/Adapter/Product/AdminProductWrapper.php` the following function calls delete all other text fields than the ones currently entered.
$product->softDeleteCustomizationFields($customization_ids); // and Customization::deleteCustomizationFieldLangByShop($customizationFiled['id_customization_field'], $shopList);
I could not find how to fix it though. 
Can anyone please help me with this asap? I'll be highly grateful.
